T 0 all whom it may concern:

Be It known that l,'Tiiou.xs M. Jnwsnn, a citizen of the United States, residing at. Chicago, in the county of Cool; and State of Illinois, have inventeo a new and useful linprovcnicnt. in Cutting Mechanism for Rolling-Mills, of which the following is a specification, accompanied by drawings forming a part of the same, in which Figure i represents a diagrammatic plan view of arroll ng mill, comprising two pairs 0t rolls and a cutting mechanism embodying my invention. Figs. 2 and 3 are respectively, plan and end views of the cuttin niechain ism. Fig. 4 is a plan view shown in section on the plane of the broken line 4- Fig. 3. Fig, 5 is a vertical sectional View on the. plane of the broken line :'i:'i, Fig. 2.

Similar reference figu es refer to similar parts in the dill'ereiit views,

The object; of my presentinvention is to provide a convenient hand operated cutting mechanism .which may be applied to the moving rod or bar of heated metal as it passes through the rolls oi" the mill, at some convenient point which'will enable the op erator to instantly sever the bar .vhciiever its forwa d movement becomes impeded, or whenever it may become necessary or any reason to sever the rod or bar in front of a air of rolls, and I accomplish this purpose y the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the acconi tianyiii; drawings 1 and 2 denote two pairs of rolls of a rolling mill through which a, rod or bar Pitt-N35 in the direction of the arrows 3, and substantially in the path of the broken line 4-. In front of and adjacent. to the rol s l, .2, l support upon the floor of the mill a cutting mechanism embodying my invention, and represented in Fi 1 at 5 and t3.

The cutting mechanisms, which in Fig. I either side of the patn of the movmg: ru

1 are'duplicates of each other. are represented upon a larger scale in Figs. 2 to 5 iiielusive. It. comprises a base 7 supported upon the floor of the mill, upon which is mounted a guide trough or channel 8 having preferably a flar ng month 9 for the reception of the rod. Between the mouth J and the gu de -:l. .anncl H is an enlarged space to receive the cutters 1U, 11, which are lt'eycd to spindles 1). and 13. The spindles also carry near their low r ends the segmental gears 14- 21ml l5, and the cutter 1015 provided with a lever handle 16, in convenient. posi tiun to be thrown from its posiiion in Figs. 2 and l to the position indicated by the broken lllhfrl 17 Fig. 4. This angular more meat of the lever liaiuliu 16 causes a siinultaueons rocking movement f the cut ers 10, 11. by means of their geared onnection i H, 1-). in which the lllltlS arose. ung from their position shown in Fig. 4 l! that ind F rated by broken lin s 12. [9, Fig. -t, in which the. cuttin; edges ar brought together against a. t'iaiigiilar stop '31.

.Vhen the cutting edges 24: have once engaged the rod, the m vement of the rod itself will serve to draw l-llv cutting edges together, iithi' position shown by the broken lines 18 and l Fig. 4, and etl'rct a complete everance of the rod.

In operation, an attendant stationed at the end of .ne cutting mechanisms. such as 5 and 6, keeps watch of the advancing rod and upon he indication of any interruption to its movement, he causes the cutters to be st ung and the rod severed.

Inasmuch as the cutting incchz-inisin may be located to receive the rod pa. Eng between two sets of rolls, there will be considerable variation, both horizontally and vertically. in the actual path of the rod which will form loops and otherwise diverge from :i dircct passage from one pair of rolls to the other. The vertical position of the spindles 1:3 and 13 and the open top of the guide channel are arranged to allow of the reinscrtion of the moving metal rod in the guide channel and between the cutters after any such variation.

I claim, v

1. In a rolling mill, the combination with a pair of rolls, a cutting mechanism located in the path of the moving metal rod about. to enter said rolls, said cutting mechanism comprising-a pair of cutters arranged upon uses and having a space between them open from above for the insertion of the moving rod, and means for operating said cutting mechanism. 7

3. In a rolling mill. the combination with a pair of rolls, a guide trough located in the path of the moving metal rod about. to enter said rolls, said guide trough open at the top to ailow the insertion of the moving rod. :1. cutting mechanism arranged to sever the rod in said guide trough, comprising a pair of cutters having a space between them open from above for the insertion of the moving rod, and means for operating said cutters.

4-. In a rolling mill, the combination with a pair of rolls, a guide trough located in the path of the moving metal rod about to enter said rolls, said guide trough open at the top to allow the insertion of the moving rod, a. 20 pair of opposing cutters rotatable around vertical axes and located on opposite sides of said guide trough having a space between them open from above for the insertion of the moving rod, and means for operating 25 said cutters.

Dated this 26th day of October 1909.
